Benefits of technology

This solution allows for efficient data read / write operations across multiple channels, reducing the overall cost of SAN systems by enabling multi-channel data access functionality within a single-channel SATA framework, enhancing data management capabilities.

Problems solved by technology

Although the hard disk equipped with SCSI can transmit data at high speed, for medium and small businesses, the SAN system is too expensive and not affordable.
This is not adequate for the SAN system as far as the transmission channel is concerned.

Embodiment Construction

[0033]Refer to FIG. 1 for the system block diagram of the invention. The system includes a first SATA control module 100, a first access-grant arbitration unit 11, a second SATA control module 200, a second access-grant arbitration unit 21 and a path selection module 30.

[0034]The first SATA control module 100 aims to control data access of a hard disk 40 (such as reading or writing). The first SATA control module 100 further includes:[0035]a first network transmission unit 10 to connect the first SATA control module 100 to a LAN 150 to transmit or receive related data and control commands. The first network transmission unit 10 includes a first Ethernet port to link the LAN 150. There is SAN system (not shown in the drawing) to do data management for the hard disk 40 through the LAN 150.

[0036]The first access-grant arbitration unit 11 located in the first SATA control module 100. It is connected to the first network transmission unit 10 and the second access-grant arbitration unit 2...

Abstract

A multi-channel serial advanced technology attachment (SATA) control system and control card thereof includes a first SATA control module, a first access-grant arbitration unit, a second SATA control module, a second access-grant arbitration unit and a path selection module. Through an arbitration process performed in the first and second access-grant arbitration units, an access-grant is determined. And a selection signal is generated based on the process result that is sent to the path selection module, to switch a transmission path to the SATA control module which has acquired the access-grant. Therefore, multi-channel SATA data access function may be achieved.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a hard disk interface control system and particularly to a multi-channel serial advanced technology attachment (SATA) control system for use in a storage area network (SAN) system.BACKGROUND OF THE INVENTION[0002]With the arrival of the information age many enterprises employ SAN systems to resolve important information management and storage problems. A SAN system is a network architecture consisting of storage equipment and is managed by a server linking to a local area network (LAN). When data is destroyed, the SAN system can provide remedy measures to restore the data to the condition before the destruction occurred. Thereby the reliability and stability of computer systems can be enhanced.[0003]In general, the transmission interface of the storage equipment (such as hard disks) being used mostly adopts the Small Computer System Interface (SCSI). Although the hard disk equipped with SCSI can transmit data at high speed...
